That's Kickstarter. GFM lets you keep any and all donations even if you don't hit your goal. It also lets you run the fundraiser indefinitely if you want to - while there can be a target date, the fundraiser won't cut off on that date.
I have no problem with his GFM. I've seen them for people wanting to buy gaming systems for their kids for Christmas or new clothes after a gastric bypass. If people want to contribute, then that's their prerogative. If you don't want to, then don't. I don't even think it's entitled - he's stated that he's working, he didn't say he'd quit if he got the money, and, to me, it never hurts to ask. I might roll my eyes at some of them, but it's not like these people are robbing you at gunpoint; just close the webpage if it's so offensive. I'm baffled why people get so worked up over them.
As for his 8 years of schooling, where are people getting that he wants to be a doctor? I didn't see him saying that anywhere? I can think of plenty of ways to hit the 8 year mark without med school. Presumably, he has his GED if he's enrolled - even at a community college. Open admission still generally requires you to have one - or they put you in the GED classes until you pass. Even with a GED though, that doesn't guarantee that he is at a collegiate level in reading/writing/math, especially as a high school drop out with a few years past him last being in school.
So, starting from the bottom level classes, at the community colleges around here, it can be nearly 2 years before you even take a college level course. 4 classes in reading/writing and 5 in math. Even taking 3 classes in both summer sessions (and some places won't let you take that many; mine allowed 4 total in the summer - 2 in each session or 4 whole summer long classes), that's still over a year just in the basics to get to a collegiate level. Now we start the "4 year" clock for a bachelors degree. With his background, he'd presumably have to 'graduate' community college with an associates degree (or have around 45-60 hours) to have a hope of transferring to a 4 year university. So 2 years for that. Now we are already up to 3.5-4 years, and he's just now getting to actual course work in his degree. Now, I had 60 hours transferred - the max allowed - but because I was going for a science (physics) degree, I still was in class with the sophmores - and not being with/under the freshmen was only because I stayed at my community college and took extra math classes to have calculus done (another 6! classes after the college algebra class required) and the freshman science classes that required calculus (2 more, after I had finished Cal 1, not offered in the summer). And if you have any kind of STEM degree, it can sometimes be more like a 5 year degree than a 4. Mine would have been, because they only offered certain senior year classes that were required once a year. If you missed it, you had to wait another year.
So, basically, 1.5 years to get to collegiate level, 2 years of generic classes to transfer to university (frosh/soph classes basically), and if he's going for any kind of STEM classes, another 1.5 years to get his math and science up to par for even transferring into the soph class, and another 3 to finish the degree. That's 8 years right there. And you can bet his advisor went over everything with him when he signed up and said "I'd like to do this in the future." I was warned the day I picked my degree how hard and how long of a slog it would be. I ended up not finishing. I hope he does. I think the discipline alone to get through all of that would do wonders for him, and the sense of accomplishment. Even if he doesn't want a STEM degree (so take away the 1.5 years to get his math and science up), the job/career he wants could require a masters. Plenty do. There's there other 2 right there. No medicine required, thank God! That is one profession I hope he stays far away from.
